2. Common triggers for the message
- Incorrect system date/time (manually mis-set or CMOS battery failure).
- Wrong timezone or mismatched daylight saving settings.
- System clock drifting due to hardware (failing CMOS battery) or virtualization host time sync issues.
- Network Time Protocol (NTP) not running, blocked, or misconfigured.
- Inability to reach time servers (firewall, proxy, or offline machine).
- License file expiry or corruption causing misleading messages.
- Virtual machines with host/guest time conflicts or snapshots restoring old timestamps.
- System locale or regional settings causing parsing mismatches in date formats.
- Software tampering detection when running a cracked/modified installation.
2. Replace CMOS Battery Proactively
- If your PC is older than 3 years, replace the CMOS battery regardless of whether you have errors. It costs $2 and saves hours of frustration.
